目的 :研究新型芳香苷类化合物葛酚苷类 ( puerosides)的波谱学特征与结构的关系。方法 :归纳了葛酚苷类化合物的紫外光谱 ( UV )、红外光谱 ( IR)、核磁共振氢谱 ( 1 H- NMR)和核磁共振碳谱 ( 1 3C- NMR)的波谱学特征。通过 CD谱数据和比旋值的直接比较确定了光学对映体 ( + ) - puerol B 2″- O- glucopyranoside与 ( - ) - puerol B 2″- O- glucopyranoside的绝对构型。结果 :( + ) - puerol B 2″- O- glucopyranoside为 4 R型 ,( - ) - puerol B 2″- O- glucopyranoside为 4 S型。结论 :光学对映体 CD谱数据和比旋值差别显著 ,对判断绝对构型具一定意义。 Objective: To study the relationship between the spectral characteristics and structure of the new type of aromatic compounds, puerosides. Methods : The spectral characteristics of the UV-spectra (UV), infrared (IR), 1 H-NMR and 13 C-NMR spectra of the glycosides were summed up. The absolute configuration of the optical enantiomer (+)-puerol B 2′′-O-glucopyranoside and (-)-puerol B 2′′-O-glucopyranoside was determined by direct comparison of the CD spectral data and the specific rotation. Results :( + )- puerol B 2′′-O-glucopyranoside was type 4 R, (-)- puerol B 2′′-O-glucopyranoside was type 4 S. Conclusion : The CD spectra of the optical enantiomers differed significantly from that of the specific rotations, which was of some significance for judging the absolute configuration.
